Exercise device

Abstract

An exercise device comprising a bar, a weight assembly, an end plate and a securing member. The bar comprises an end portion onto which the weight assembly is mounted. The securing member co-operates with the end plate to secure the weight assembly to the end portion of the bar. The end plate is rotationally fixed relative to the weight assembly to mitigate against loosening of the securing member during use.

1. An exercise device comprising:
 a bar, the bar having an end portion; 
 a weight assembly mounted on the end portion, the weight assembly including a weight section and an outer skin; 
 an end plate; and 
 a securing member for co-operating with the end plate to secure the weight assembly to the end portion of the bar; 
 wherein a recess is formed in the outer skin of the weight assembly and is configured to receive the end plate, and the end plate and the recess are configured such that a portion of the end plate interlocks with a portion of the recess to rotationally fix the end plate relative to the weight assembly. 
 
     
     
       2. The exercise device of  claim 1 , wherein the end plate comprises a first engagement element, and the weight assembly comprises a corresponding second engagement element, and wherein the first and second engagement elements, in use, engage to prevent relative rotation between the end plate and the weight assembly. 
     
     
       3. The exercise device of  claim 2 , wherein the first engagement element comprises at least a portion of the end plate, and the second engagement element comprises at least a portion of the recess. 
     
     
       4. The exercise device of  claim 3 , wherein the first engagement element comprises at least one projection and the second engagement element comprises at least one receiving section corresponding to the projection. 
     
     
       5. The exercise device of  claim 4 , wherein the at least one projection is integral with the end plate. 
     
     
       6. The exercise device of  claim 4 , wherein the end plate comprises a load plate and an end plate outer skin, and the at least one projection is formed by the end plate outer skin. 
     
     
       7. The exercise device of  claim 6 , wherein the end plate outer skin is moulded over the load plate, the at least one projection being formed by the moulding process. 
     
     
       8. The exercise device of  claim 4 , wherein the at least one receiving section is formed by the recess. 
     
     
       9. The exercise device of  claim 4 , wherein the at least one projection includes a radial projection. 
     
     
       10. The exercise device of  claim 3 , wherein the shape of the end plate defines the first engagement element, and the shape of the recess defines the second engagement element. 
     
     
       11. The exercise device of  claim 2 , wherein the recess comprises at least one projection defining the second engagement element, and the end plate comprises at least one corresponding receiving defining the first engagement element. 
     
     
       12. The exercise device of  claim 1 , wherein the outer profile of the end plate and the inner profile of the recess are the same. 
     
     
       13. The exercise device of  claim 1 , wherein the end plate comprises a pair of radially opposed projections defining the first engagement element, and the recess comprises a pair of receiving sections corresponding to the pair of projections defining the second engagement element. 
     
     
       14. The exercise device of  claim 13 , wherein the pair of projections include a pair of radial projections. 
     
     
       15. The exercise device of  claim 1 , wherein the outer skin is moulded over the weight section, with the recess being formed during the moulding process. 
     
     
       16. The exercise device of  claim 1 , wherein the securing member includes a screw member. 
     
     
       17. The exercise device of  claim 16 , wherein the end portion comprises an internal threaded portion adapted to receive the screw member. 
     
     
       18. The exercise device of  claim 1 , further comprising a second securing member for securing the weight assembly to the end portion, wherein the first and second securing members each independently secure the weight assembly to the end portion. 
     
     
       19. The exercise device of  claim 1 , wherein the exercise device is a dumbbell. 
     
     
       20. The exercise device of  claim 1 , wherein the recess is adapted to prevent relative lateral movement between the end plate and the weight assembly.
